This figure shows the volcanic peak Idunn Mons on Venus. The colored area represents information gathered by spacecraft to tell scientists about slight temperature variations around the volcano. These colors would not be seen by the human eye.

The colors indicate the composition of the minerals that were changed due to interaction with the atmosphere. Red-orange is the warmest and most recent area and purple is the coolest and oldest. The warmest area is centered on the summit, which stands about 2.5 kilometers (1.6 miles) above the plains. Idunn Mons has a diameter of about 200 kilometers (120 miles).
